Modeling perception is critical for many applications and developments in computer graphics to optimize evaluate content generation techniques. Most of the work date has focused on central (foveal) vision. However, this insufficient novel wide-field-of-view display devices, such as virtual augmented reality headsets. Furthermore, perceptual models proposed fovea do not readily extend off-center...

Abstract For a continuous core-periphery model, we construct model with n regions for each $$n\ge 2$$ n ≥ 2 . Assuming that the known functions of and diameters converge to 0 respectively as number tends infinity, this paper proves approximate relations...

Two concepts of centrality have been defined in complex networks. The first considers the centrality of a node and many different metrics for it has been defined (e.g. eigenvector centrality, PageRank, non-backtracking centrality, etc). The second is related to a large scale organization of the network, the core-periphery structure, composed by a dense core plus an outlying and loosely-connecte...

The concept of nestedness, in particular for ecological and economical networks, has been introduced as a structural characteristic of real interacting systems. We suggest that the nestedness is in fact another way to express a mesoscale network property called the core-periphery structure. With real ecological mutualistic networks and synthetic model networks, we reveal the strong correlation ...
